How can I make more secure passwords that I can still remember?

This link below leads to a few simple systems described in a paper titled “Simple Formula for Strong Passwords: Dramatically Increase Information Security with Minimal Training, and Without Costly Infrastructure Changes.” (It’s a 42 page PDF.)

Slightly off topic, but if you must write a password down, see if you can write only part of it, just enough to help you remember the rest.
